The results assess the traditional use of A. cherimola as an antidiabetic agent. suggest that rutin; an α-glucosidase inhibitor was responsible in part of Materials and Methods: The ethanol extract from A. cherimola (300 mg/ the antihyperglycemic activity of A. cherimola. Its in vivo antihyperglycemic kg, EEAc), subsequent fractions (100 mg/kg), and rutin (30 mg/kg) were activity is in good agreement with the traditional use of A. cherimola for the studied on alloxan-induced type 2 diabetic (AITD) and normoglycemic treatment of diabetes. rats. In addition, oral glucose tolerance test (OGTT) and oral sucrose tolerance test (OSTT) were performed in normoglycemic rats. Molecular docking technique was used to conduct the computational study. Results: Bioassay-guided fractionation of EEAc afforded as major antihyperglycemic compound, rutin. EEAc attenuated postprandial hyperglycemia in acute test using AITD rats (331.5 mg/dL) carrying the glycemic levels to 149.2 mg/ dL. Rutin after 2 h, attenuated postprandial hyperglycemia in an acute assay using AITD rats such as EEAc, with maximum effect (150.0 mg/dL) being seen at 4 h. The antihyperglycemic activities of EEAc and rutin were comparable with acarbose (151.3 mg/dL). In the subchronic assay on AITD rats, the EEAc and rutin showed a reduction of the blood glucose levels since the 1st week of treatment, reaching levels similar to normoglycemic Abbreviations Used: EEAc: The ethanol extract from Annona cherimola, state (116.9 mg/kg) that stayed constant for the rest of the assay. OGTT AITD: Alloxan-induced type 2 diabetic rats, OGTT: Oral glucose tolerance and OSTT showed that EEAc and rutin significantly lowered blood glucose test, OSTT: Oral sucrose tolerance test, DM: levels in normoglycemic rats at 2 h after a glucose or sucrose load such as Diabetes mellitus Access this article online Website: www.phcogres.com acarbose. Computational molecular docking showed that rutin interacted Correspondence: with four amino acids residues in the enzyme α-glucosidase. Conclusion: Dr. Fernando Calzada Bermejo, Quick Response Code: The results suggest that rutin an α-glucosidase inhibitor was responsible Unidad de Investigación Médica en in part of the antihyperglycemic activity of A. cherimola.

However, DM and its secondary complications Cite this article as: Calzada F, Solares-Pascasio JI, Ordoñez-Razo RM, continue to be a major problem in the world population.

Antihyperglycemic activity pharmaceutical drugs are either too expensive or have undesirable side of the leaves from Annona cherimola miller and rutin on alloxan-induced diabetic effects. In the case of acarbose is a well-known α-glucosidase inhibitor rats.

In this sense, medicinal plants are one of the Balb-C mice of either sex (20 ± 4 g) were used. Animals were raised in the useful areas of this research since they constitute an important source Animal House of the National Medical Center “Siglo XXI” from IMSS. of new compounds with potential therapeutic effects.[15] In the case of [16] Investigations using experimental animals were conducted in accordance México, a total of 306 species are used for the treatment of diabetes. by the Official Mexican Rule.[45] They were maintained in a temperature Annona cherimola Miller is one of the many edible fruits species in the room (22°C ± 2°C) on a 12 h light-dark natural cycle. Rodents were fed Annona genus that belongs to the Annonaceae family in the Magnoliales with standard diet and water ad libitum. These studies were conducted with order. It is a semi-deciduous, erect, but low-branched tree, frequently the approval of the Specialty Hospital Ethical Committee of the National branched off at ground level. The plant is native of Ecuador and Peru Medical Center “Siglo XXI” from IMSS (Register: R-2012-3601-18). distributed widely in the tropical or subtropic regions from America, Africa, and Asia and even in the South of Europe.[17,18] In México is Acute oral toxicity study popularly known as “chirimoya, atish (Michoacan), tzon te chkia The acute oral toxicity study was conducted using test guidelines on (Oaxaca), lamatzapotl (Puebla), and yati (Veracruz)”. This species, acute oral toxicity test 423 according to OCDE (2001).[46] Twenty-four alone or in combinations with others have been used in Mexican Balb-C mice fasted overnight but allowed free access to water ad libitum traditional medicine for the treatment of several diseases such as fever, were randomly assigned into the following four groups of six mice of cough, worms, and headache as well as anti-inflammatory. In addition, either sex (three males and three females). Control received distilled to treat gastrointestinal disorders such stomach pain, diarrhea, and water and three groups received the extract at the doses of 30 mg/kg, [16,19,20] dysentery; at present, it is used to treat diabetes. Phytochemical 300 mg/kg and 3000 mg/kg. The mice were not fed for 4 h following [20-24] investigations revealed the presence of alkaloids, flavonoids, sterols, administration. The signs of toxic effects and/or mortality were observed [25-27] [28,29] [30,31] terpenoids, cyclic peptides, and acetogenins. With regard 4 h after administration then, for next 48 h. The general behavior of mice to pharmacological investigations have been reported that A. cherimola was observed daily in a period of 14 days for mortality, toxic effects, [31-33] [23] extracts possess genotoxic, cytotoxic, antihypercholesterolemic, and/or changes in behavioral pattern. At the end of the experiments, [34] [22] [35] [25] antihyperlipidemic antidepressant, cryoprotective, anxiolytic, the animals were sacrificed in a CO chamber. Then, the internal organs [36] [37] [38] [17,20] 2 antiprotozoal, antisecretory, antiarthritic, antibacterial, (stomach, gut, lungs, kidney, heart, spleen, and liver) were extracted, and [17] [39,40] antifungal, anti-inflammatory, antioxidant, and inhibitor of the pathological observations were performed. mitochondrial complex I properties.[30] In addition, antihyperglycemic activities of the ethanol extract of the leaves from A. cherimola Induction of experimental diabetes in rats [41,42] (EEAc) have been reported.
